Very Cool Slant 6 Product! Camshaft Button
I use a "Poke it down the middle" (3 bolt cam) version that i made from nylon , on a hemi 6, same style pressed steel cover
never had a problem.
was simpler than chrylser Australias Service bulletin which suggested brazeing a nut to the cover and using a bolt with the end concaved for a steel ball bearing.
Not aware of anyone ever having a cracked or compromised cover due to this mod.
see here.
and here, anceint web site not secure some virus scanners will block you because it is not HTTPS and it has daft geocity web ring adverts. so "1990's"
DR.HEMI Hemi 6 Camshaft End Float Restrait
am aware of people having the chain or sproket carve the front of the cover out, becase they didn't do this mod.
with a gear drive, if the teeth of the gear are true and the cam floats as it should agints lifter/lobe profile and pump or dizzy gear reaction, the button should just work in the same way.
the fluted covers seem to be robust enough
coll product
sensible addition provided it doesn't undo the cam bolt. which is highly unlikley
